AbstractAbstract PDF
To evaluate the intractability of partial epileptic patients by variables, the author studied 113 patients (uncontrolled: 45, controlled: 68) who were admitted to the Department of Neurology, College of Medicine, Yeungnam University from January, 1991 to August, 1993. The results were as follows. The items related to complex partial seizures, multiple seizure types and a histories of status epilepticus or clusters of seizures were significantly associated with drug-refractoriness (p<0.01). A high frequency of seizures before evaluation was associated with a poor outcome(p<0.01). The presences of known etiology of seizures, neurologic abnormalities and psychiatric disturbance were associated with limited treatment responses(p<0.01, p<0.05, p<0.01). An abnormal EEG findings such as background slowing, focal slowing, epileptiform discharges or secondarily bilateral synchrony were statistically significant (p<0.01). Age at onset, sex, distribution of epileptic foci, duration of seizure before evaluation, family history and abnormal neuroradiologic findings were not statistically significant. By these results, it was suggested that having at least four factors of the above variables were associated with limited treatment response.

AbstractAbstract PDF
The purpose of this study was to evaluate the effect of stroke on hypothalamic-pituitary axis using dexamethasone suppression test. The effects were evaluated according to age, sex, type, size, and lesion site of stroke. There tests were performed in 62 patients with stroke(cerebral infarction, 42 cases : intracerebral hemorrage, 20 cases) and 21 disabled controlled patients without intracranial diseases at Yeungnam University Hospital from June 1992 to June 1993. The results summarized as follows. 1. Cerebral infarction showed significantly higher frequency of DST non-suppression in stroke patients than control (p<0.05). 2. Patients with left hemisphere stroke showed more frequent abnormal neuroendocrine test results (p<0.01). 3. Patients with large infarction revealed strongly non-suppressed DST results(p<0.01). 4. Significantly higher basal cortisol level in patients with cerebral infarction was noted(p<0.01). 5. There are no statistical significance between DST results and sex, age, motor impairment, type of cerebral infarction.

AbstractAbstract PDF
The author studied 20 healthy adults (20 hands) as a control and 30 patients (40 hands) with carpal tunnel syndrome to evaluate the clinical usefulness of measuring nerve conduction velocity after wrist flexion in diagnosis of carpal tunnel syndrome. The median nerve conduction velocity over wrist to finger segment was measured before and after wrist flexion for 1, 2 and 5 minutes, using belly-tendon method for motor nerve distal latency (MNDL) and antidromic method for sensory nerve conduction velocity (SNCV). The results were as follows: 1. In control group, MNDL increased in 1 hand and SNCV decreased in 2 hands after wrist flexion. In patient group, MNDL increased in 2 hands and SNCV decreased in 3 hands after wrist flexion. 2. In both control and patient group, there were no significant changes in mean values of SNCV and MNDL between before and after wrist flexion. 3. Phalen's wrist flexion test was positive in 5 percent of control and 60 percent of patient group. 4. Tinel's sign was present in 10 percent of control and 33 percent of patient group.

AbstractAbstract PDF
The diagnosis of OPCA could be made clinically with important aid of brain CT scanning, although the definite and conclusive diagnosis only by postmortem pathological determination. We reviewed, clinically and with brain CT examination, 12 cases of patients with OPCA who were admitted to the Yeungnam University Hospital for a recent 5 years. The result were as following: 1. The distribution of age is from 49 to 72, mainly 50 to 60. Man is more frequent than women at the 4.5 times. 2. The interval period from Sx. Onset to diagnosis is 1 year to 6 years. 3. The usual initial Sxs. Were dizziness (58%), ataxia (33%), and other less frequent Sxs. Were weakness of low extremities, dysarthria, headache and urinary incontinence. The clinical manifestations at the initial diagnosis were cerebellar disturbance (100%), dysarthria (83%), and increased deep tendon reflexes (58%). 4. The results of brain CT finding are like this: the width of cerebellar sulci is more than 1mm, other 4 cases more than 2mm. the width of cerebellar pontine cistern of the patient if usually 3 to 4mm, other 2 cases extended to the 5 mm. the A. P and lateral lengths of 4th. ventricle is 4 mm and 4 to 8 mm respectively. 6 cases of whole patients show coincidentally cerebral atrophy.
